What Does 200/85R16 Actually Mean?

Let's break it down simply: The 200 means this tire has a tread width of 200 millimeters. The 85 is the aspect ratio, which means the sidewall height is 85% of that width. The "R" stands for Radial construction (the modern standard for safety and durability), and finally, the 16 indicates that this tire perfectly fits a 16-inch wheel.
